' To all whom it may concern:

*Be it known that I, MAUR'. E HQUDAILL a citizen of the French Republic, residing in 'Levallois-Perret, France,.have invented a certain-new and useful Wiping Device for Screens and the like, of which the following is a specification.

This invention relates to a device for wiping glass screens or the like, and according to the invention the screen is constituted by a revolving disk driving with a rapid rotary movement brushes arranged on both sides of the said disk.

The device is more particularly applicable to the windows of locomotives or other vehicles, and other surfaces liable to collect soot or other adhesive dust which cannot be removed by simple wiping, though it is not limited to these applications.

A construction according to the invention.

intended to receive a driving belt 18operated by any suitable transmission gear.

At each side of its center, the glassl is provided with a'bevelwheel v19 with which engage a series of small bevelpinions 20 mounted respectively on radial rods 21 arranged in a triangular'case 22. These rods have around eachyof them and along the whole of their length, vegetable or metal brush elements engaging with the two faces of the glass. Along one of the edges of each of the sides of the case 22, is arranged a perforated tube 31 terminating at the discharge tary brushes.

branch of a centrifugal pump 23 immersed in a water tank 24 arranged below the case 22. The water contained in the said tank 24, is mixed with potash or any other detergent. A metal netting 25 is arranged in the tank 24 above the pump 23, between the latter and the case 22 containing the ro- The sides of the case 22 are provided with rubber scrapers 26 in contact with the two faces of the rotary glass 1.

The pump 23 is driven by a pulley 27 arranged on a counter shaft 28 driving also the rotary glass 1 by means of another pulley 29 and receiving its movement from the driving transmission by a pulley 30. In

these conditions, whenthe glass 1 and the pump 23 are driven, water is projected through the tubes 31 against the two faces of the glass 1, while the wheels 19 driven by the glass 1, act on the pinions 20 in order to impart a rapid movement of rotation to the brushes which thus clean the glass. movement of rotation is imparted to the glass sothat the portions to be cleaned, come first under the brushes, so that soot and other impurities detached by the said brushes but remaining on the glass, are held back by the scrapers 26 and then fall on the metal netting 25. Thisnetting is detachable so that it can be easily removed and cleaned.

The tank 24 can be fed with water either continuously or intermittently by means of a conduit 31 terminating at the said tank. The excess of water escapes through the conduit 32.

What I claim as my invention and desire to secure by Letters Patent is 1. In a device for wiping glasses, transparent screens and the like, a rotary glass disposedin an opening made in a fixed glass,

. driving means acting on the circumference of the glass, rotary cleaning brushes applied to both faces of the glass, driving means for said'brushes, a case surrounding said brushes, a water tank forming the lower portion of the case, means driven by the mechanism 'which drives the glass for impinging water upon the glass, and a netting arranged in the upper portion of the tank for separating dirt and water coming from the cleaning brushes.

2. In a device for wiping glasses, transparent screens and the like, a rotary glass disposed in an openingmade in a fixed glass, driving means acting on the circumference of the glass, rotary cleaning brushes applied to both faces of the glass, driving means for said brushes, a case surrounding said brushes, a water tank forming the lower portion of the case, means driven by the mechanism which drives the glass for impinging water upon the glass, rubber scrapers fixed to the case and engaging the glass at both sides, and a netting arranged in the upper portion of the tank for separating dirt and water coming from the cleaning brushes.

3. In a device for wiping glasses, trans parent screens and the like, a rotary glass disposed in an opening made in a fixed The glass, rollers inserted between the fixed glass and the rotary glass, a ring in which the glass is set, a grooved pulley formed with the ring, a driving pulley supported in a recess of the fixed glass, a driving belt passing over the pulley and the grooved pulley of the movable glass, rotary cleaning brushes applied to both faces of the glass, bevel pinions secured to the said brushes, a central spindle for the glass, bevelwheels secured to the central spindle and engaging with the pinions of the said brushes a case surrounding the bevel wheels and also the vbrushes, a water tank forming the lower portion of the case, a pump arranged in the said tank and driven from the driving pulley, perforated conduits projecting the water discharged by the pump against the two faces of the glass, and a netting arranged in the upper portion of the tank for separating dirt and water coming from the cleaning brushes.

In testimony whereof I have signed my name to this specification in the presenceof two subscribing witnesses.
